Engineering Selection Recommendations

PS7141EL-2A-A (CEL): Product status is Obsolete. REACH Affected. Recommended for legacy system maintenance only where original part specifications are mandated.

AQW214EHA (Panasonic Electric Works): Product status is Active. ROHS3 Compliant. REACH Unaffected. Provides improved on-state resistance (35 Ohms vs. 50 Ohms) with matching load current capability (100 mA) and input voltage specification (1.14 VDC). Moisture Sensitivity Level is Not Applicable, providing superior environmental performance. Recommended as primary substitute for new designs and legacy replacements.

PVT422SPBF (Infineon Technologies): Product status is Active. ROHS3 Compliant. REACH Unaffected. Delivers increased load current capability (120 mA vs. 100 mA) and improved on-state resistance (35 Ohms vs. 50 Ohms) while maintaining identical input voltage specification (1.2 VDC). Moisture Sensitivity Level MSL-4 requires appropriate handling. Recommended for applications requiring increased load current margins.

Frequently Asked Questions (FAQ)

Q: Can the AQW214EHA substitute the PS7141EL-2A-A in all applications? A: Yes. The AQW214EHA meets all critical parameters: identical circuit configuration, package, termination style, voltage ratings, and load current specification. The lower on-state resistance (35 Ohms vs. 50 Ohms) represents improved performance. Input voltage 1.14 VDC is within acceptable tolerance of the 1.2 VDC requirement.

Q: What is the difference in load current between the PVT422SPBF and the original PS7141EL-2A-A? A: The PVT422SPBF is rated for 120 mA versus the PS7141EL-2A-A's 100 mA. This 20 mA additional capacity provides margin in designs operating near the 100 mA limit. Applications below 100 mA operate within the original specification.

Q: Are there moisture sensitivity considerations for substitute selection? A: The AQW214EHA specifies Moisture Sensitivity Level as Not Applicable, providing unrestricted storage and handling. The PVT422SPBF specifies MSL-4 (72 Hours), requiring controlled humidity storage and handling conditions within 72 hours of package opening prior to reflow soldering. The original PS7141EL-2A-A specifies MSL-1 (Unlimited). Environmental conditions must align with manufacturing process requirements.

Q: Do all substitute components have identical electrical performance characteristics? A: The on-state resistance differs: PS7141EL-2A-A is 50 Ohms (Max), while both AQW214EHA and PVT422SPBF are 35 Ohms (Max). This represents lower conduction losses in the substitutes. All components maintain identical voltage ratings and circuit configuration. The PVT422SPBF has 20 mA additional load current capacity.

Q: What is the primary reason the PS7141EL-2A-A requires substitution? A: The PS7141EL-2A-A is classified as Obsolete, indicating discontinued manufacturing and unavailable inventory replenishment from the original manufacturer CEL. Substitute components from active manufacturers ensure long-term procurement availability and supply chain continuity.
